beta is a portuguese slang that characterizes rich white girls from Cascais (rich coast city in lisbon) who vape iqos, think they're better than everybody else, and are daddy's girls. They usually carry bimba y lola bags and daisy print skirts
It also has a masculine equivalent: beto
Girl- Look at Maria do Mar and her bimba y lola.
Boy- She's such a beta, right?
